Hello,

I am working on atomization of liquid jet.I am using mixturemultiphase model model, I am having 1 continuous phase(air) and 10 particle phases (water).I am using an UDF to model the breakage process. When I ran the simuation at default densities air 1.225 and water 998.2 ,I could get a really good solution based on mass balance( 1e-3%), I then changed the density of air to 49.91 to change liquid air density ratio to 20. I am doing this to compare my solution to literature ,I am using velocity of water as 100m/s and velocity of air 0 m/s (quiescent air).

I tried reducing is the UR's my solution is diverging, which should not happen when UR's are reduced. My flow field doesn't make sense in this case. I am completely struck at this point ,no idea of what is causing the problem. can anyone help me with your expertise ???

Thanks
